HGAC
The COHGIS (City of Houston GIS) Open Data Portal website provides over 100 data sets including administrative boundaries, amenity locations, transportation routes, crime, and flooding. For this tutorial, we will download population and housing data from the 2010 census, which has been aggregated to super neighborhood boundaries.
- Using a web browser, search for "houston hgac gis census data" and select the result as shown below or or go directly to: https://cohgis-mycity.opendata.arcgiswww.h-gac.com/census-data.
ADD SCREENSHOT ON MAC (ARJUN)
Whenever you see a URL that ends in opendata.arcgis.com, you will know that you are visiting a standard ArcGIS Open Data portal. - If you are looking for specific data, you can enter a term in the search box, but if you would like to see the full data catalog, click the Search button without entering a search term. You can then browse through the full list of data or filter by topic on the left side.
In this case, we are looking for census data by super neighborhood. To learn more about super neighborhoods, visit the City of Houston Super Neighbhorhoods webpage. - In the 'Find' box, type "census 2010 by super neighborhood" and press Enter.
- Click Census 2010 By SuperNeighborhood, as shown below.

HCAD and COHGIS
Though it is not used in this course, the Harris County Appraisal District (HCAD) Public Data and the COHGIS (City of Houston GIS) Open Data Portal are other great online sources.
HCAD Data is another great online source that provides similar data such as highways, utilities, and water districts and is available at: http://pdata.hcad.org/GIS/index.html.
The COHGIS (City of Houston GIS) Open Data Portal website provides over 100 data sets including administrative boundaries, amenity locations, transportation routes, crime, and flooding and is available at: https://cohgis-mycity.opendata.arcgis.com/.
OPTION 2: Accessing tutorial data from Fondren Library using the gistrain profile

- In the Catalog pane, click the Major_Roads geodatabase feature class from the Major_Rivers.gdb and drag-and-drop it into the Intro.gdb. A progress bar will appear that reads 'Copying...' Once it is complete, you will see a copy of Major_Roads inside the Intro.gdb as shown below.
- Census_1010_By_SuperNeighboorhood, METRO_BusRoutes, and METRO_BusStops are Shapefile feature classes, so these Shapefiles require a different method to be imported into the Project Geodatabase. In the Catalog pane, right-click on Census_1010_By_SuperNeighboorhood.shp and select Export > Feature class(es) to geodatabase.
- In the Geoprocessing pane, click the Folder button to the right of the blank input features drop-down.
- In the 'Input Features' window, click Project > Folders > Downloads in the right column and click Open.
- Select METRO_BusRoutes.shp and METRO_BusStops.shp and click OK.
- In the Geoprocessing pane, accept default settings as shown below and click Run.
- In the Catalog pane, right-click on Intro.gdb and select Refresh.
Your Project Geodatabase should now contain four Geodatabase feature classes: Major_Roads, Census_1010_By_SuperNeighboorhood, METRO_BusRoutes, and METRO_BusStops.
- In the Catalog pane, in the Folders section, right-click on Downloads and select Remove.
